![]() I believe that a high end MPPT charge controller will make your batteries last longer and produce more kWh per useful life than investing in a BMS for any series or series parallel strings of any type of lead acid battery. Off grid for 20 years (if I include 8 months on a bicycle). I also use a part of the potential of a monster Aims 12kW inverter to run my whole house for 6 to 8 hrs when the sun shines and keep the batteries above 70% state of charge unless I have to go deeper overnight in a power outage.SLA obviously don't require watering or equalizing but FLAdo stay well balanced if you equalize them every month or two.īack to your question. Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites, Midnite E-panel, Magnum MS4024, Prosine 1800 (now backup) and Exeltech 1100 (former backup.lol), 660 ah 24v Forklift battery (now 10 years old). ![]() I installed a watering manifold on the batteries and I give them a drink about once a month. I have had really good luck with strings of 8 (8s)Trojan T105s and a Morningstar Tristar 60 MPPT fed by 6X265 watt Canadian solar panels. Spend your money on a custom configurable charge controller that can be tuned exactly to your solar/generator/turbine and exactly to the battery manufacturers specs. I would rarher prefer to monitor the batteries live.Ĭlick to expand.Possible? sure. Your suggestion of disconnecting each battery is a lot of work, and a lot of downtime each time I have to switch everything off, disconnect, etc, etc. When I go over to 2V cells, I would hopefully be able to reuse the same monitoring system if it can read as low as 1.8V. Getting back to your original statement about being able to monitor the cells. Aliexpress has some balancers for 12V batteries. This means that if the 24V section shows problems, I won't know which one of the two 12V batteries has a problem.īalancing them would be my next quest. ![]() The two perform similar functions, but MPPT is typically the better. Victron has a monitor for this but it doesn't work well in a 48V environment since it only monitors three points, which in this case means 0V - 24V - 48V. Our 30-amp dual battery bank charge controller can regulate and monitor the charge. But if I could monitor all 16 batteries, reporting to Grafana, I would be able to pickup a problem before it gets out of hand. Temperature Effects & Battery Voltage Sense. View online or download Morningstar TriStar TS-60 Installation, Operation And Maintenance Manual, Quick Start Manual. Since the batteries are sealed, there's not much I can do from a cell level. Morningstar TriStar TS-60 Pdf User Manuals. With either of these options, you’ll be able to monitor system performance, albeit without the ability to change system settings remotely. I set this for the standard Crown battery setting and then increased the P1 voltage setting to 14.8V so that it will still work on very short winter days. ![]() Read my MidNite page and look at the last picture there. Different brands and models exist in South Africa, like the Trojan R105-E of Omnipower 200A, etc. Alternatively, Morningstar offers controllers with out-of-the-box ethernet capabilities, such as the Morningstar TriStar TS-MPPT-60 Charge Controller. I still love the Morningstar Tristar for larger systems, using a Trimetric for metering. ![]()
